DC LENS
These are special lenses that are designated for digital cameras
because the lens image circle is designated to correspond to the
size of the image sensors of most digital SLR cameras. The
specialized design gives these lenses the ideal properties for digital
cameras.
◆ An image sensor element larger than those corresponding to
APS-C cannot be used in digital cameras or 35mm SLR cameras.
If such an element is used vignetting will occur on the picture
surface.
◆ If you use SD9, SD10 or SD14 digital cameras, corresponding
angle of view will be 17-34mm.
ATTACHING TO CAMERA BODY
When this lens is attached to the camera body it will automatically
function in the same way as your normal lens. Please refer to the
instruction booklet for your camera body.
◆ On the lens mount surface, there are a number of couplers and
electrical contacts. Please keep them clean to ensure proper
connection. To avoid damaging the lens, be especially sure to
place the lens with its front end down while changing the lens.
SETTING THE EXPOSURE MODE
The sigma lens functions automatically after mounting to your
camera. Please, refer to the camera instruction book.
FOCUSING AND ZOOMING
This lens features Sigma’s built-in Hyper Sonic Motor (HSM). The
HSM enables quick and quiet autofocusing.
《SIGMA AF and CANON AF》
For autofocus operation, set the focus mode switch on the lens to
the “AF” position (fig.2). If you wish to focus manually, set the focus
mode switch on the lens to the “M” position. You can adjust the
focus by turning the focus ring.
《NIKON AF, PENTAX AF and SONY》
For autofocus operation, set the camera to AF mode and set the
focus mode switch on the lens to the “AF” position (fig.2). If you
wish to focus manually, set the focus mode switch on the lens to the
“M” position. You can adjust the focus by turning the focus ring.
◆ Please refer to camera’s instruction manual for details on
changing the camera’s focusing mode.
◆ For Nikon, Pentax and Sony mounts, it is only possible to use AF
with camera bodies which support motors driven by ultrasonic
waves such as HSM. AF will not function if the camera body does
not support this type of motor.
◆ This lens also permits manual focusing even in the autofocus
mode. With the camera set to the One-Shot AF (AF-S) mode, it is
possible to manually override the autofocus while the shutter
release button is pressed halfway.
◆ When operating this lens in manual focus mode, it is
recommended that correct focus be confirmed visually in the
viewfinder rather than relying on the distance scale. This is due to
possible focus shift resulting from extreme changes in
temperature which cause various components in the lens to
expand and contract. Special allowance is made for this at the
infinity setting.
《Zooming》
Rotate the Rubber grip on the zoom ring to the desired position.
FLASH PHOTOGRAPHY
Built-in flash of your camera may not cover angle of view of this
lens, and this may cause light fall-off at the corners. When external
flash is used, flip wide panel of your flashgun down to cover flash’s
head, before taking picture. (This may not work with some
flashguns, please test your equipment shootings beforehand)
LENS HOOD
A bayonet type detachable hood is provided with the lens. This lens
hood helps to prevent flare and ghosted images caused by bright
illumination from outside the picture area. Attach the hood and turn
clockwise until it stops rotation. (fig.3)
◆ In order to place the lens and hood into the storage case, you
must first remove the hood, then replace it on the lens in the
reverse position. (fig.4)
FILTER
◆ Only one filter should be used at the time. Two or more filters
and/or special thicker filters, like a polarizing filter, may cause
vignetting.
◆ When using a polarizing filter with AF camera, use the “circular”
type.
BASIC CARE AND STORAGE
◆ Avoid any shocks or exposure to extreme high or low
temperatures or to humidity.
◆ For extended storage, choose a cool and dry place, preferably
with good ventilation. To avoid damage to the lens coating, keep
away from mothballs or naphthalene gas.
◆ Do not use thinner, benzine or other organic cleaning agents to
remove dirt or finger prints from the lens elements. Clean by
using a soft, moistened lens cloth or lens tissue.
◆ This lens is not waterproof. When you use the lens in the rain or
near water, keep it from getting wet. It is often impractical to
repair the internal mechanism, lens elements and electric
components damaged by water.
◆ Sudden temperature changes may cause condensation or fog to
appear on the surface of the lens. When entering a warm room
from the cold outdoors, it is advisable to keep the lens in the case
until the temperature of the lens approaches room temperature.
